使用Pandas和Matplotlib绘制Candlestick_OHLC一分钟的条形图

您需要将日期转换为mdates.date2num,因为

时间必须是浮动日格式 - 请参阅date2num

然后我尝试实现这个解决方案:

import pandas as pd

import matplotlib.pyplot as plt
from matplotlib.finance import candlestick_ohlc
import matplotlib.dates as mdates

#if necessary convert to datetime
df.date = pd.to_datetime(df.date)

df = df[['date', 'open', 'high', 'low', 'close', 'volume']]
df["date"] = df["date"].apply(mdates.date2num)

f1 = plt.subplot2grid((6, 4), (1, 0), rowspan=6, colspan=4, axisbg='#07000d')
candlestick_ohlc(f1, df.values, #53c156', colordown='#ff1717')
f1.xaxis_date()
f1.xaxis.set_major_formatter(mdates.DateFormatter('%y-%m-%d %H:%M:%S'))

plt.xticks(rotation=45)
plt.ylabel('Stock Price')
plt.xlabel('Date Hours:Minutes')
plt.show()
